title: Palladium(II)-catalyzed ortho-arylation of benzylic phosphonic monoesters using potassium aryltrifluoroborates.
abstract: The new monophosphonic acid directing group was successfully utilized in the Pd (II)-catalyzed ortho-arylation of benzylic phosphonic monoesters using potassium aryltrifluoroborates. A wide range of benzylic phosphonic monoesters underwent clean ortho-arylation in high yields, and excellent functional group tolerance was also observed.
